Jyotsna Nitika Diamonds, July 29th , 2017. So far, we have discussed diamonds that can be found on earth. However, carbon, being a highly common element in the universe, diamonds may also be created in extraterrestrial environments. For instance, meteorites may contain diamonds. Meteorites are pieces of metal, rock and other elements that have entered the earth from outer space. When a meteor of considerable size enters the earth's atmosphere, a large amount of heat is generated due to friction. In addition, the impact that is caused when they strike the earth will also create massive amounts of heat and pressure. Once again, when the conditions are just right, the crater that results from the meteor strike may contain small diamonds. In addition, diamonds may already be present on meteors and survive the impact. Of course, meteorite diamonds are even rarer than naturally created mined diamonds.

Then, try to keep the diamonds as sparkly as possible by wiping with a clean cloth and storing in a clean, safe and secure place.
Mari Holzer Diamonds, July 30th , 2017. One of the biggest selling points of diamonds is its clarity. It is colorless. Simulants due to the chemicals used to manufacture them often have traces of colors. Simulated diamonds do not possess the clarity of genuine diamonds. Most simulants have tints of colors like gray or yellow. You may come across diamond simulants that reflect light in a vivid manner but you will definitely see tints of color. Diamond is one of the hardest materials that occurs naturally. It is unlikely that you will be able to scratch the diamond with anything other than another diamond. A simulant is hardly ever free of external flaws. The easiest way to distinguish between real diamonds and simulants is to conduct a scratch test or consult a gemologist.
Ivona Gita Diamonds, July 28th , 2017. Natural diamonds are ideally mined at depths between 140-190 km in the Earth's mantle region. They are retrieved from carbon-containing minerals, that are formed over billions of years. The ores containing these carbon minerals are usually part of the spewed magma that surfaces during volcanic eruptions. They cool to form igneous kimberlite and lamproite rocks. Synthetically, diamonds are produced by using a high pressure and temperature, and exposure to chemical vapor. Synthetic diamond variants such as the cubic zirconia and silicon carbide are created to replicate appearance and properties of real diamonds. A cut is done to shape a diamond, prior to polishing the stone. There are a number of cuts adopted to make jewelry with diamonds, such as:

Euanthe Alya Diamonds, July 28th , 2017. One has to be very careful while shopping for a chocolate diamond. Some jewelers make fake brown colored diamonds by exposing diamonds of lower grade to radiations and changing the color to brown. Such diamonds look like the original ones but they are not valuable and have no resale value. You must remember to buy the stone from a trusted jeweler. It is also essential to get a certificate signifying the diamond's origin which will prove its authenticity.
Rashmi Jameela Diamonds, July 30th , 2017. Today, many of the worlds pink sapphires originate in Madagascar from a recently discovered large deposit, making the usually rare pink sapphire a more accessible and far more affordable gemstone. But even so, today, pink sapphires are still valuable, and are very often more expensive than high quality dark or royal blue sapphires. African sapphires cover almost the full spectrum of colour, but are usually smaller in size than those from other regions. Ceylon is also a rich source of pink diamonds; with gemstones from this region exhibiting a tinge of blue, which give them a slightly more purplish hue. Ceylon produces many pretty shades of pink sapphire. Other valuable sources of the rare pink sapphire include Australia, Brazil, Burma, Thailand, and Vietnam. The difference between a pink sapphire and a ruby is very difficult to determine and, at times, almost impossible.
Mari Holzer Diamonds, July 29th , 2017. Diamond earrings are also available in yellow gold. It is relatively cheaper than platinum and white gold. The carat range in yellow gold is 10k, 14k, 18k, and 24k. 24k gold is the purest form, but the diamond jewelry in yellow gold is only designed in 14k and 18k. This gold adds a vintage look to the earrings. The yellow gold jewelry is undoubtedly the classiest as it has been in use since ages, even before platinum and white gold were discovered.
Yehudit Laine Diamonds, July 29th , 2017. Perceived to be one of the safest stones known to man, the stone is known for its neutral effects to those it might not suit and superlative effects to those it does; it is no wonder that this gemstone reigns supreme in terms of being expensive, second only to the diamond. It helps increase your financial status, empowering you in more ways than you can imagine.

Corina Marisol Diamonds, July 28th , 2017. Earlier because of lack of modern technologies, the only source of diamonds was the natural source that is mining the diamond mines or digging the earth's crust to find the valuable stone. Also, the diamonds found with the natural ways were of high quality and did not contain any sort of deformation or contamination. They were in the purest forms. But, with the changing times and with the advancement in the technology, the world has found many types of machinery and equipment for developing the diamonds with artificial ways. Though, the pressure and temperature conditions are kept the same.
